* Allow ISA bus to be configured outDavid Gibson2017-02-061-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the code to handle the legacy ISA bus is always included in qemu. However there are lots of platforms that don't include ISA legacy devies, and quite a few that have never used ISA legacy devices at all. This patch allows the ISA bus code to be disabled in the configuration for platforms where it doesn't make sense. For now, the default configs are adjusted to include ISA on all platforms including PCI: anything with PCI can at least in principle add an i82378 PCI->ISA bridge. Also, CONFIG_IDE_CORE which is already in pci.mak requires ISA support. We also explicitly enable ISA on some other non-PCI platforms which include ISA devices: moxie, sparc and unicore32. We may want to pare this down in future. The platforms that will lose ISA by default are: cris, lm32, microblazeel, microblaze, openrisc, s390x, tricore, xtensaeb, xtensa. As far as I can tell none of these ever used ISA. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Acked-by: Michael S.
